Can some one help me find out the price for a baseball card?

Question

It is a 1988 Carl William Mays, part of the Conlon Collection (Baseball Immortals).

It was left in a car given to us and the previous owner told us anything that was left in the car was ours if we wanted it.

Im not sure where to look online to find information about this card, so any sites your could give me that would have the price guide for this card would be truly appreciated.
